‘100 GB of daily data’: ESA’s Euclid Telescope sends back images of 26 million galaxies in dark universe

First Euclid Data

Mapping the Large-Scale Structure

Observing the Deep Universe

AI-Assisted Galaxy 

Galaxy Evolution

A Long-Term Mission

Knowledge of Cosmology

The European Space Agency (ESA) has released the first dataset from the Euclid space telescope, which is designed to study dark matter and dark energy. The data includes scans of three deep-field regions and classifications of over 380,000 galaxies, representing just 0.4% of the expected total over the mission’s six-year lifespan.


The first survey data from the 600-megapixel Euclid space telescope is available now. Euclid observed 26 million galaxies in total in just one week. Watch this report for more details!

Telescope's first survey finds 26 million galaxies in 1 week

<p>The Euclid Space Telescope revealed the “first page” of the world’s largest 3D map of the universe on Tuesday&nbsp;(Oct 15). The first look of the cosmic atlas features tens of millions of stars within the Milky Way and around 14 million distant galaxies beyond our own.&nbsp;</p>

<p>The Euclid mission was launched in 2023 by the European Space Agency (ESA) with contributions from NASA. The American space agency sent the first snapshots of&nbsp;the mission in November 2023 and then in May 2024.&nbsp;</p>

<p>This mission aims to make a 3D cosmic atlas in the time and space of the universe, which will help in revealing the mysteries of dark energy and dark matter, that together make up 95 per cent of the universe.</p>

Euclid telescope sends stunning test pictures back home from space. Have a look

<p>Euclid, a groundbreaking space telescope named after the Greek mathematician Euclid, has embarked on an extraordinary million-mile journey from Florida as it sets out to unravel the mysteries of the universe. This two-tonne probe, part of a $1 billion European Space Agency mission, was launched into space aboard Elon Musk's SpaceX Falcon 9 rocket from Cape Canaveral at (11:11 AM local time) or 8:41 PM IST.</p>

<p>The telescope will be dispatched to an observing position 1.5 million kilometres away from Earth.</p>

<h2><strong>What's the objective of the mission?</strong></h2>

<p>The primary objective of Euclid is to observe and study the large-scale structure of the Universe. Equipped with advanced instruments such as the Visible instrument (VIS) and the Near Infrared Spectrometer and Photometer (NISP), it will provide us with invaluable insights through visible imagery, near-infrared spectroscopy, and photometry.</p>

<p>By mapping the vast structure of the universe, including the distribution of galaxies and other matter on a grand scale, Euclid aims to enhance our understanding of the evolution of the cosmos. Additionally, it seeks to shed light on the role of dark energy and dark matter in the expansion of the universe.</p>

<p>One of the key tasks of Euclid is to measure the redshifts of galaxies. Redshift is the phenomenon where the light emitted by galaxies is stretched as the universe expands. By analysing the redshifts, scientists can determine the distances to galaxies and accurately map the distribution of matter throughout the universe.</p>

<p>The month-long journey of Euclid marks an important milestone in the quest to explore the vastness of space. Its scientific endeavours will not only deepen the knowledge of the universe's structure but also provide crucial insights into the fundamental forces that shape its existence.&nbsp;</p>

<h2><strong>Launch impacted by Russia-Ukraine conflict</strong></h2>

<p>It must be noted that the Euclid telescope was&nbsp;originally scheduled to launch on a Russian Soyuz rocket from the European spaceport in Kourou, French Guiana. However, the plan was modified after Russia launched its invasion of Ukraine, putting the project in a tight spot.&nbsp;Giuseppe Racca, Euclid’s mission manager at ESA in Noordwijk, the Netherlands, said, "We were faced with possibility of putting the spacecraft in storage and launching in three to four years.”<br />
<br />
